db_r50_icdar15.yaml 单卡eval 当pretrained: True 时 正常
复现命令示例：python /data3/cty/mind_lab/test_mindocr/mindocr/tools/eval.py -c /data3/cty/mind_lab/test_mindocr/mindocr_models_test_data/db_r50_icdar15/test_eval_db_r50_icdar15_ascend_icdar15_1p_graph_001/db_ricdar15.yaml > case.log 2>&1
具体问题：eval 会被 pretrained: True影响 必须 pretrained: False才能正常eval，这应该不合理，eval应该和 pretrained无关，需要解耦吧？当pretrained: True 时eval具体报错如下：
==> Dataset output columns:
['image', 'polys', 'ignore_tags']
